It's just about moving a dependency up a level of node_modules if they are compatible. So if for example 2 packages A and B have the same dependency on babel-core, instead of node_modules/A/node_modules/babel-core and no

You don't have to use Babel, but if you want to use newer/syntax not in Node/v8 then yes. Always a tradeoff, but gave a talk at TC39 recently about this, https://github.com/hzoo/role-of-babel-in-js , htt

Yeah it's definetely a lot of work on both ends (also means would need to coordinate releases of both like we do with flow) but hopefully this helps the ecosystem that wants to use both (seems to be an increasingly higher number of peo

Yep, and we (Babel) are trying to work with TS on integrating it into Babel similar to how flow works with Babel (parser support + a plugin/preset to strip types). Again, limited resources so if the community really wants it, we would

I haven't heard of this either. I guess they just wanted something that worked with minimal effort. Making the plugin and writing/coming up with spec tests takes time but albeit a better effort for the community overall. Maybe we

Thanks! Will be working torward making the preset-env + babel-minify combo work much better soon.

FYI we do have an issue open about TS https://github.com/babel/babylon/issues/320 so that we could eventually support TS in Babel as a plugin and then create the same strip-types-plugin just like Flow.

We don't support custom syntax that isn't already a proposal (meaning it has potential to be in JS), and we also encourage using presets like https://github.com/babel/babel-preset-env instead of providing you

The purpose of Babel/transpilers is to eventually allow users to use the native versions of language features. Native support will eventually be faster (not at first), will result in less code sent to users (compiled code is larger), a

Yep and with Babel we recommend using https://github.com/babel/babel-preset-env to compile only what's missing in the targets you support. Hopefully we have a better solution about making multiple bundles (separat

For JavaScript we have https://github.com/estree/estree as our JS AST spec for parsers like esprima, acorn, babylon (under a config flag), etc. JSCS ( https://github.com/jscs-dev/node-jscs ) (now me

https://github.com/babel/babel-preset-env/ should help with this to remove the polyfills that are already supported, and with some future work to remove polyfills are unused.

Might be a good chance to suggest using our new preset: https://github.com/babel/babel-preset-env/ . TL;DR - automate your Babel config options based on targets. babel-preset-env: A Babel preset that can automatica

Awesome! What's one of them? Hope to see you around then!

Author here, if anyone had questions or wanted to know more about how to help out! Personally, I'm most excited about babel-preset-env, and fixing how we work with the TC39 process via experimental plugins, and working with the commun

Haha fixed - or it can be a joke on the output being larger.

There's actually a useBuiltins option to remove the _extends helper if you want to use that. https://babeljs.io/docs/plugins/transform-object-rest-spread... Might be cool in combination with preset-env

You might be interested in https://github.com/babel/babel-preset-env :D. (I'm working on it so let me know if you have questions)

I think it depends on the project like mentioned. For react, the docs for the website is in the same repo as the main code under "docs/" https://github.com/facebook/react/tree/master/docs .

This is a great start! Contributing can be a lot more than just PRs though: - answering questions on stack overflow, chat (irc, gitter, slack) - creating a minimal code repro, checking for duplicates, checking if a bug is fixed in a later

Not the best way to find an open source project to contribute to but you can check trending per language https://github.com/trending/csharp or the top starred repos that are C# https://github.com/search

Right! And a lot of projects have a linter in place that runs in continuous integration (travis, etc) that you can see in the PR or just locally. In Babel we use ESLint for this https://github.com/babel/babel/blob&
